 Refugium
I am having a difficult time trying to decide on what type of refugium to build. I have a 30 gal. 36"long tank.
The three types are:
1) Hang on Back - a)small, b)easy to set up, c)powered by powerhead and therefore inexpensive, d)small critters can flow into display unharmed.
2) Above tank - a)larger, b)must have enough pump power to overcome head height, c)small critters can flow into display unharmed, d)must have some way to break siphon in case of power outage.
3) Below tank - a)large as whatever fits, b)can accomodate heater and skimmer, c)need more powerful pump to overcome head height, d)must have overflow box, d)chews up critters on return to tank.
At the moment, I am considering building a separate stand for another aquarium to be at the same height as my display tank and therefore function as a HOB only not "hanging". |
